A method is provided for forming a multi-media communication path between at least first, second and third communication devices coupled to a multi-media provider system during post answer call redirecting and/or teleconferencing. The method includes receiving and processing a first call request at a circuit-based portion of the multi-media provider system for forming a first communication link between the first and second communication devices. Thereafter, predetermined attributes of the first communication link may be sent to an IP-based portion of the multi-media provider system for configuring the IP-based portion of the multi-media provider system to process a subsequent request to execute post answer call redirecting and/or teleconferencing. Upon detecting the request to execute the post answer call redirecting and/or teleconferencing in the first communication link, the IP-based portion of the multi-media provider systems responds by forming the multi-media communication path between at least first, second and third communication devices.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for providing Post Answer Call Redirection (PACR) to provide capacity relief to an existing telecommunications network and to predetermined network elements, the method comprising: a. receiving at a Border Element (BE) attributes associated with a telephone call established in a circuit switched network from a calling party; b. transmitting a message from the Border Element to a Call Control Element (CCE) to a Service Broker (SB) to an Application Server (AS) to a Media Server (MS), wherein a first query message is received by the AS without having been routed through a circuit-based portion of the existing telecommunications network and including a circuit switch, a circuit service control point (SCP), and a circuit adjunct; c. receiving at a Border Element instructions for PACR from the AS; d. providing PACR, via a combination of the AS, the MS, the BE, and the CCE without accessing the circuit switch, the circuit SCP, or the circuit adjunct; and e. after receiving PACR, routing a re-directed telephone call without accessing the circuit switch, the circuit SCP and the circuit adjunct.
